Abciximab (ReoPro) is the Fab fragment of the chimeric human-mouse monoclonal antibody 7E3. It avidly binds to both glycoprotein IIb/IIIa and to integrin αvβ3, and so would potentially inhibit both erythrocyte binding to vascular endothelial as well as platelet adhesion, thus targeting two separate mechanisms that are felt to be components of the vaso-occlusive phenomenon in SCD.
